A breakthrough in China’s green hydrogen technology is set to transform the global energy landscape. Scientists in Rizha, Shandong Province, have developed a plant that can convert seawater and industrial electricity into three outputs: drinking water, green hydrogen, and mineral-rich salts.
The innovation comes at a time when the world faces two major crises: the decline of fossil fuels and a growing global water shortage. With rising demand for clean energy and potable water, this plant offers a cost-effective and environmentally friendly solution. Each cubic meter of seawater can be processed at just 2 euros—around 24 Bangladeshi taka—far cheaper than Saudi Arabia at 42 taka and California, USA, at 186 taka.
The most significant output is green hydrogen, a pollution-free fuel produced through renewable electricity-driven water electrolysis. This hydrogen can power buses, vehicles, factories, and electricity generation. The Rizha plant has an annual capacity of approximately 192,000 cubic meters of green hydrogen, enough to drive 100 buses around 3,800 kilometers each year.
Historically, producing hydrogen from seawater faced challenges. Salt, magnesium, and chloride ions would damage equipment. China’s new technology eliminates the need for purified water. Machines can run continuously for three weeks without maintenance. This “zero waste” process ensures maximum energy efficiency and no harmful byproducts.
Besides fuel, the plant produces clean drinking water and mineral-rich salts. This dual-purpose output addresses both energy and water scarcity challenges. Experts say this technology could redefine global energy systems, providing a sustainable alternative to oil and fossil fuels.
The development is not just a national achievement but a potential game-changer for the future of energy worldwide. By turning seawater into green hydrogen, China reduces dependence on oil, lowers carbon emissions, and offers a sustainable path for transportation and industry.
Analysts highlight that the technology aligns with global efforts to combat climate change and prepare for future water shortages. With operational costs significantly lower than international alternatives, this model can be scaled to coastal regions around the world.
China’s breakthrough shows that clean, renewable energy from seawater is no longer theoretical. It opens doors to a future where fuel and drinking water come from abundant natural sources, creating opportunities for energy independence and environmental sustainability.
As global demand for energy and water grows, the Rizha plant demonstrates that innovation can tackle multiple crises simultaneously. With seawater as a future fuel source, the world may enter a new technological era, reducing conflicts over fossil fuels and prioritizing sustainable solutions.
